Bridge rate-limiter / chain-pause as positive mitigant

Usual (USD0 / bUSD0 / USUAL)'s assessment for RD-F-185 — scored red on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

No rate-limiter documented for USD0 LayerZero OFT adapter (0xE14C486...). Usual tech docs do not describe a per-window outflow cap on cross-chain OFT transfers. Ethereum mainnet has no chain-level pause capability. No positive mitigant identified for cross-chain bridge outflows. Red — absence of mitigant.

Methodology #

Determine whether the bridge implements a per-window outflow rate-limiter (and at what cap), and whether the protocol team can trigger a chain-level or validator-set emergency pause.
